这是一个有趣的问题，我会尽力解释。如果您有任何疑问，请询问。
我编写了一个 WCF 服务，它应该与 JAVA 客户端进行通信。该服务首先是通过合同从 WSDL 创建的。现在，根据 WCF 测试客户端，一切正常，即使在 PHP 客户端上进行测试也可以正常工作。但是当涉及到 Java 客户端时，请求消息和后续响应消息都无法返回：我得到一个空对象 SOAP 错误。这是我认为问题所在：
根据 XSD 和 WSDL，我有一个我应该接受的 DateTime 值。来自客户端的这个 dateTime 值的格式为：2012-01-01T12:00:00.00Z。不幸的是，此输入对内置的 .NET 日期时间无效。因此，为了解决这个问题，我将代码更改为采用字符串数据类型，将该字符串转换为 Datetime 以将其发送到数据库，在该 dateTime 中从数据库获取响应并将其转换回用于响应的字符串返回一个与输入的值类似的值。
我构建了一个记录器来检查是否正在向我的 wcf 服务发送消息和从我的 wcf 服务发送消息。由此，我发现没有收到来自客户端的消息。我唯一的猜测是这是因为日期时间问题。
有没有办法接受格式为：2012-01-01T12:00:00.000Z 的 dateTime 数据类型？如果可以，那将意味着该请求将与我的数据类型匹配，并且可能会起作用。
这是一些代码：
